"most men who exercise regularly and don't carry a ton of extra bodyweight, even with zero running" - what's that supposed to mean? How do they exercise then when they are not running?
I don't think many people who don't exercise running can do 1.5 miles in 9:40.
It's 1.5 miles in 14:25, I think most people can handle that. There are plenty of ways to exercise that aren't plain running. Biking, skating, swimming, Tai chi...
